Efficient and Rapid Fiber Ball Filler
Polyester fiber property:
Strength | 4-6g/denier higher one time than cotton and higher 3 times than wool |
Hygroscopicity | 0.4%-0.5% (20°CRH65%) |
Relative humidity | 100% |
Proportion | 1.38g/cm³ |
Hot property | Softening point: 238-240 Melting point: 255-260 |
Resistance to solar | Good |
Acid resistance | 35%HCL 75%H2SO4 65%HNO3 No effect on the strength |
Alkali resistance | 10%NaOH 28%NH3H2O No effect on the strength |
Abrasive resistance | Good |
Microorganism resistance | No mould ,no moth |
Filter material characteristics:
Soft,compress and large void volume,strong sewage interception ability;filter layer interspace thin on the top and thick on the buttom,according with ideal filter material layer interspace spread. Proportion is a litter higher than water,easy to backwash. With good material and strong abrasive resistance and strong chemical erosion resistance ability.
Several filter material void volume comparison:
Filter material | Magnetite sand | Sand | Open font coal | Tattered shale plumbago | Fiber ball |
Total void volume | 49.5% | 50% | 51.3% | 70.3% | 92-95% |
